Abstract
Description
- The invention relates to a railroad tie of compact design for a fixed track with an overlay of asphalt of the Getrac construction with a dowel stone, which is inserted in a recess on the underside and which, reaching over the railroad tie and protruding downward, engages a cavity pocket of the asphalt track.
- In the case of railroad ties of compact design for fixed tracks of Getrac construction, a very high surface pressure results when normal railroad ties are used. As a consequence, over time, the railroad tie is pressed more and more into the asphalt, so that the height adjustment of the cast track is lost. In the case of the Getrac system, the cavity pocket of the asphalt track is to be filled after the railroad ties or a premanufactured track grid are aligned, in order to anchor the dowel stone, since, after all, the cavity pocket must be constructed larger initially in order to be able to compensate for manufacturing and laying tolerances. This, however, presupposes, in turn, that the cavity pocket protrudes somewhat laterally beyond the railroad tie, as clean casting can otherwise not take place.
- It is therefore an object of the invention to configure a railroad tie of compact design for a fixed track with an overlay of asphalt of the Getrac construction in such a manner, that less surface pressure is present and, nevertheless, it is possible to fill the cavity pockets of the asphalt track after the railroad ties are aligned.
- Pursuant to the invention, this objective is accomplished owing to the fact that the railroad tie of compact design is formed as a double railroad tie, between which and the adjacent railroad tie there is only a small gap, which enables a curve to be laid, and which, in the region of the dowel on the underside, is provided with lateral constrictions for filling the cavity pockets subsequently.
- Instead of the normal, wide railroad ties of compact design previously used, double railroad ties are employed pursuant to the invention, the width of which is such, that they in each case form only a narrow gap with the neighboring railroad tie. By these means, the surface pressure evidently becomes very much less and the danger of sinkage into the asphalt does not exist here. Due to the lateral constrictions in the region of the dowel stone, which are unusual in the case of double sleepers laid on track ballast, the cavity pockets of the asphalt track, which are in the region of these constrictions, are exposed at least at the outer edge, so that, in spite of almost the complete coverage of the asphalt track by the double railroad ties, the cavity pockets of the asphalt track can still be filled subsequently and, with that, the dowel stones, engaging therein, can be anchored.
- Moreover, the inventive use of the special double railroad ties also has the advantage that, due to the great weight of the railroad ties, the load on the dowel stone in the transverse and longitudinal directions is less, since the weight of the railroad ties alone largely absorbs the direct transfer of forces as a carriage passes over the railroad ties.
- Moreover, it is also within the scope of the invention to provide the inventive double railroad tie in the region of the pocket accommodating the dowel stone with a cavity of low height, which extends over the whole width and also over a greater length than does the recess for the dowel stone. This cavity prevents the railroad tie being supported precisely in the middle and, with that, also the danger of breakage. Moreover, due to this gap, air can escape through this gap while the cavity pocket of the asphalt track is being filled, so that this filling can take place more quickly and more uniformly.
- Further advantages, distinguishing features and details of the intervention arise out of the following description of an example and the drawing, in which
- FIG. 1 shows a section through a fixed track with a partially broken open railroad tie of compact design, constructed as a double railroad tie,
- FIG. 2 shows a plan view of the track of FIG. 1 and
- FIG. 3 shows a section through the double railroad tie along the line III-III of FIG. 2.
- The construction of a fixed track with an asphalt overlay of the Getrac A3 construction can be seen best in FIG. 1. The lower supporting
layer 1, on which two differently constructedasphalt layers nonwovens fabric 6 is disposed between theupper asphalt layer 3 and theinventive railroad tie 4 of compact design, which is constructed pursuant to the invention as a double railroad tie so that there is only a small gap between it and the neighboring railroad tie. As is customary in the case of fixed tracks of the Getrac A3 construction, the inventive, double railroad tie is provided with adowel stone 7, which is held with the help of an elastic ring bearing 8 in arecess 9 on the underside of the railroad tie. This dowel stone engages alarger cavity pocket 10 of theasphalt layer 3, the exact position, occupied by this cavity pocket, resulting only during the adjustment of the track grid. For this reason, thecavity pocket 10 is also constructed larger. After the adjustment, thiscavity pocket 10 is once again filled with asphalt. For this purpose, thecavity pocket 10 must, of course, be open at the top. Pursuant to the invention, this is achieved owing to the fact that the double railroad tie is provided in the region of thedowel stone 7 withlateral constrictions cavity pocket 10 is open at its upper ends, so that the subsequent filling of thecavity pockets 10, after the adjustment of therailroad ties 4, is assured in spite of the otherwise almost complete coverage of theasphalt track 3. - In the region of the
constrictions double railroad tie 4 is provided on the underside with acontinuous depression 13 of low height, which extends over the whole width. On the one hand, this prevents the railroad tie being supported in the center and, with that, prevents the danger of breakage. On the other hand, while thecavity pockets 10 are being filled with asphalt, air can escape through thisgap 13, which is open towards of the side in the region of thepockets
